For this reason, even if the urging means 43 is provided, the opening / closing operation of the back door 4 is not deteriorated.

  Next, the opening / closing operation at the time of opening / closing of the tonneau cover device configured as described above will be described with reference to schematic schematic diagrams of FIGS. FIG. 11 is a schematic diagram of a state in which the tonneau cover device is completely closed, FIG. 12 is a schematic diagram of the first stage of the opening process, FIG. 13 is a schematic diagram of the second stage, FIG. 14 is a schematic diagram of the third stage, and FIG. FIG. 16 is a schematic diagram of a fourth stage, and FIG. 16 is a schematic diagram of a state in which the tonneau cover device is completely opened. In addition, about the component of each figure, the code | symbol same as the component demonstrated so far is attached | subjected, and description is abbreviate | omitted.

As shown in FIG. 11, at the stage of completely closing the back door 4, the back door 4, since the wire member (not shown) is not lifted, slider member 41 is located below. For this reason, both the front tonneau cover 20 and the rear tonneau cover 30 are deployed in a substantially horizontal state above the cargo compartment T and completely cover the cargo compartment T.

  In this state, the position of the front tonneau cover 20 is defined by the shelf 6, the first board 21 and the second board 22 are in a low position, the fourth board 24 is in a high position, and the third board 23 is in the front. It is defined in the downward slope position.

  That is, the shelf 6 is formed as a front lower step 61, a rear upper step 62, and a forwardly inclined portion 63 at an intermediate position, so that the front tonneau cover 20 is positioned as a "backward raised step shape". It is prescribed as follows.

  As described above, since the position of the front tonneau cover 20 is defined, the front tonneau cover 20 described below can be bent.

On the other hand, the rear tonneau cover 30, the sheet member 32 is pulled out halfway, and developed as a backdoor 4 side is slightly lower.

Next, as shown in FIG. 12, in the slightly open out the back door 4, the wire member (not shown) Along with being pulled upward, slider member 41 is moved slightly upward. Therefore, the winding unit 31 presses the fourth board 24 forwardly One or upward from the rear, bending deformation occurs between the rear end 23a of the front end 24a and the third board 23 of the fourth board 24.

  As described above, the mountain breakage deformation is caused by the fact that the front tonneau cover 20 is positioned as a stepped shape that rises rearward by the shelf 6 described above.

  That is, the fourth board 24 is held at a high position, and the third board 23 is tilted forward and held, so that the fourth board 24 is interposed between the fourth board 24 and the third board 23 as shown in FIG. Has a bending angle α on the lower side. Since the bending direction of the board member is defined by the bending angle α, the bent portion P having the bending angle α becomes a “trigger” of the mountain folding, and the mountain bending deformation occurs.

Furthermore, the bending deformation, the position of the engagement boss portion 36 of the winding unit 31, i.e., is promoted by coupling position between the slider member 41 of the winding unit 31 (the point of application of force).
That is, as shown in FIG. 11, assuming a dynamic board member B on the line connecting the position of the engagement boss part 36 and the bent part P, the virtual board member B and the third board 23 The bending angle β formed between them is further reduced. For this reason, it becomes easier to produce the mountain break deformation in this bending part P, and a mountain break is accelerated | stimulated.

  As described above, the mountain-fold deformation between the fourth board 24 and the third board 23 is determined by the installation angle of the third board 23 and the position of the engagement boss portion 36 of the winding unit 31. It can be seen that the position of the engagement boss portion 36 of the winding unit 31 is set larger and lower than the plane extension line Q extending from the line 23.

Next, as shown in FIG. 13, in yet stage of opening the back door 4, slider member 41 is slid to substantially the middle position, the winding unit 31 is moved upward One or forward. Along with this, the fourth board 24 is pressed forward, and the mountain breakage deformation with the third board 23 further occurs.

  At this time, the seat member 32 of the rear tonneau cover 30 to which the back door 4 is fixed follows the opening operation of the back door 4 and is pulled out largely rearward.

Then at the opening phase of the back door 4 as shown in FIG. 14, and slid further upward slider member 41, the winding unit 31 is also moved upward One or forward. Then, the winding unit 31, by pulling upward displacement and sheet member 32 of the fourth board 24, the upper is rotated so as to shift forward (see arrow).

The sheet member 32 drawn from the winding unit 31 also will be drawn greatly One or rearwardly upward, will follow the opening movement of the back door 4.

Furthermore, at the opening phase of the back door 4 as shown in FIG. 15, and slid further upward slider member 41, the winding unit 31 while moving upwardly One or forward, to rotate forward. Then, not only the fourth board 24 and the third board 23 but also the second board 22 is displaced upward so that the rear end 22 a of the second board 22 follows the front end 23 a of the third board 23. Be raised.

Finally, at the fully open state of the back door 4 as shown in FIG. 16, slider member 41 is moved to the upper end of the slide rail 8, the winding unit 31 will be located at the top One or foremost.

  Then, the front tonneau cover 20 leaves the first board 21 and the other second board 22, third board 23, and fourth board 24 are displaced upward, and the rear tonneau cover 30 has the sheet member 32 as well. It expands greatly upward and expands in a screen shape in a substantially vertical direction.

  Thus, the front tonneau cover 20 can expand the opening TO at the rear of the cargo compartment T by the displacement of the second board 22, the third board 23, and the fourth board 24. Easy to put in and out. Further, since the sheet member 32 of the rear tonneau cover 30 is developed in a screen shape in a substantially vertical direction, the sheet member 32 does not protrude downward from the inner side surface of the back door 4, and the operator The head member and the sheet member 32 do not interfere with each other.

Next, the function and effect of the present embodiment configured as described above will be described in detail.
In this embodiment, a pair of left and right slide rails 8 extending forward and backward in the vertical direction on the rear pillar 7, and a front portion that is connected to the slide rail 8 at the rear end and extends substantially horizontally above the rear floor panel 2. a tonneau cover 20, a rear tonneau cover 30 provided with a retractable seat member 32 the rear end is connected to the back door 4 is provided at the rear end of the front tonneau cover 20, the rear end of the front tonneau cover 20 and A slide mechanism 40 such as a slider member 41 that moves the front end of the rear tonneau cover 30 up and down along the slide rail 8 is provided.

Thus, the slide mechanism 40 causes the rear end of the front tonneau cover 20 and the front end of the rear tonneau cover 30 to move up and down obliquely in conjunction with the opening and closing operation of the back door 4.
For this reason, the front tonneau cover 20 does not protrude outward (rear) side of the cargo compartment T, and does not interfere with the quarter window glass 5 on the side surface of the cargo compartment T. Further, since the rear tonneau cover 30 is constituted by the wind-up type seat member 32, the rear tonneau cover 30 is pulled out so as to follow the rear end of the front tonneau cover 20 even when the back door 4 is opened. The tonneau cover can be positioned on the front side of the vehicle rather than the one that is fixed to the back door as a board member.
Therefore, when the back door 4 is opened, the rear tonneau cover 30 does not protrude downward and is positioned on the front side of the vehicle. Therefore, the operator's head and the seat member 32 interfere with each other when the luggage is taken in and out. Even if they interfere with each other, the sheet member 32 has flexibility, so that the operator does not feel pain. Furthermore, since the seat member 32 does not protrude below the back door 4, the appearance when the back door 4 is opened can be improved.
Therefore, at a position above the rear part of the luggage compartment T, the tonneau cover device 10 of a vehicle installed substantially horizontal deployed condition, in accordance with the opening and closing operation of the back door 4, the front tonneau cover 20 and the rear tonneau cover 30 In addition to being configured to be lifted upward, when the back door 4 is opened, the loading and unloading work can be easily performed, and the appearance can be improved.

Further, in this embodiment, the front tonneau cover 20 is constituted by board members (21, 22, 23, 24).
Thereby, the luggage compartment T at the rear of the vehicle body covered with the front tonneau cover 20 is covered with the rigid board members (21, 22, 23, 24).
For this reason, in the state which developed the front part tonneau cover 20 in the luggage compartment T, the appearance in the luggage compartment T can be improved. Further, the front tonneau cover 20 can also be used as a storeroom above the cargo compartment T.
Therefore, while the tonneau cover device 10 is deployed, the appearance in the cargo compartment T can be improved and the functionality of the tonneau cover device 10 can be further enhanced.

Further, in this embodiment, the side recess 37 that prevents interference with the side edge BE of the vehicle body opening BO on the rear surface of the vehicle body is formed in the seat member 32 of the rear tonneau cover 30 when the back door 4 is opened.
Thereby, when the back door 4 is opened, the drawn-out seat member 32 and the side edge BE of the vehicle body opening BO do not interfere with each other.
Therefore, the pulled-out seat member 32 does not damage the side edge BE of the vehicle body opening BO, and the pulled-out seat member 32 is not caught by the side edge BE, so that the rear tonneau cover 30 can be pulled out. The sheet member 32 can be reliably pulled out without being obstructed.
Therefore, even if the rear tonneau cover 30 is constituted by a retractable seat member 32 and is drawn out when the back door 4 is opened, the side edge BE of the vehicle body opening BO is not damaged, and The drawer operation can also be performed smoothly.

In this embodiment, the mesh member 38 is provided on the sheet member 32 of the rear tonneau cover 30.
Thus, even when the seat member 32 is pulled out when the back door 4 is opened and deployed in a screen shape between the vehicle compartment on the vehicle front side and the vehicle rear side, the vehicle compartment side and vehicle from what Re of the rear side, it is possible to secure the visibility.
For this reason, the operator can communicate with the passenger in the vehicle compartment when taking in and out the luggage, and the operator behind the vehicle can be easily confirmed from the passenger in the vehicle compartment.
Therefore, even when the seat member 32 of the rear tonneau cover 30 is developed in a screen shape when the back door 4 is opened, information can be easily exchanged between the vehicle interior and the rear of the vehicle, and safety can be improved. .
In addition, since the same effect can be acquired even if it has permeability other than the mesh part 38, for example, using an opening hole and a slit, and further, using a transparent sheet member, a translucent sheet member, etc. Also good.

Further, in this embodiment, the front tonneau cover 20 is constituted by a plurality of board members (21, 22, 23, 24) arranged in the front-rear direction, and the front tonneau cover 20 is located along the slide rail 8 above. When moving, it is configured to bend between the third board 23 and the fourth board 24 on the rear side of the vehicle body.
Thereby, the board members (21, 22, 23, 24) of the front tonneau cover 20 are moved forward by bending between the two board members (the third board 23 and the fourth board 24). The rear opening TO (see FIG. 16) can be enlarged.
Therefore, the opening part TO at the rear of the luggage compartment T can be enlarged without greatly raising the front tonneau cover 20 upward.

Further, in this embodiment, the bending of the third board 23 and the fourth board 24 is particularly set so as to be mountain-folded.
That is, in order to set a “trigger” for the mountain break deformation, the fourth board 24 is positioned at a high position, and the third board 23 is positioned so as to be inclined downward in front of it.
For this reason, the front tonneau cover 20 is positioned as a “step shape” with the board member (24) on the rear side being higher, so that the appearance of the tonneau cover device 10 in the luggage compartment T can be improved.
Therefore, the appearance in the luggage compartment T can be improved while the front tonneau cover 20 can be bent.

Further, in this embodiment, the side panel 3 on the side surface of the cargo compartment T is inclined with respect to the shelf 6 that causes the mountain break deformation between the third board 23 and the fourth board 24, specifically, the upper stage 62. A portion 63 is formed.
Thereby, with respect to the front tonneau cover 20, it is always possible to cause the mountain break deformation stably.
For this reason, even if the front tonneau cover 20 itself is not provided with a mechanism for causing the mountain break deformation, the front tonneau cover 20 can be sure to cause the mountain break deformation.
Therefore, the structure of the front tonneau cover 20 can be configured in a simple structure, the front tonneau cover 20 can be manufactured inexpensively One or lightweight.

Further, linkage in this embodiment, at a lower position than the plane extension Q (see FIG. 11) of the third board 23 of the front tonneau cover 20, the engagement boss portion 36 of the winding unit 31, the slider member 41 is doing.
Accordingly, when the winding unit 31 moves forward and obliquely upward along the slide rail 8, the engagement boss portion 36 serves as a point for pushing up the fourth board 24 from the lower side to the front tonneau cover 20. It is possible to surely cause mountain breakage deformation.
Therefore, the fourth board 24 of the front tonneau cover 20 has a rear end that is pressed from below and moves upward so that the front tonneau cover 20 can be reliably bent and deformed.

In this embodiment, the front tonneau cover 20 is provided with a first board 21 and a second board 22 in addition to the third board 23 and the fourth board 24 that are bent and deformed.
Thereby, the wider range above the cargo compartment T can be covered with the board members (21, 22, 23, 24) of the front tonneau cover 20.
Therefore, the opening TO at the rear of the luggage compartment can be enlarged with a degree of freedom of folding while covering the wider range above the cargo compartment T with the front tonneau cover 20.

Further, in this embodiment, the front tonneau cover 20 and the rear tonneau cover 30, and removable with respect to the vehicle body.
Thereby, the front tonneau cover 20 and the rear tonneau cover 30 can be removed from the luggage compartment T when the front tonneau cover 20 and the rear tonneau cover 30 are not used.
Therefore, when the tonneau cover device 10 is not used, the cargo space can be widely used, and the cargo space can be expanded.

In this embodiment, the first board 21 of the front tonneau cover 20 is provided with a hinge pin 27a that is fixed to the vehicle body side.
Thereby, the first board 21 at the foremost position of the front tonneau cover 20 is always fixed to the vehicle body side when the tonneau cover device 10 is mounted.
For this reason, the position of the front tonneau cover 20 at the time of mounting is reliably defined by the first board 21 not involved in the enlargement of the opening TO at the rear of the cargo compartment T, and the bending point of the front tonneau cover 20 can be reliably defined. .
Therefore, the bending point of the front tonneau cover 20 can be reliably defined while the front tonneau cover 20 and the like can be removed, and the deformation operation of the front tonneau cover 20 can also be reliably caused.

Further, in this embodiment, the front tonneau cover 20 and the rear tonneau cover 30, it is foldably configured (see FIG. 10).
Thereby, the big tonneau cover apparatus 10 can be folded compactly in the state removed from the vehicle body in the unfolded state.
Therefore, the front tonneau cover 20 and the rear tonneau cover 30 can be compactly stored in the sub trunk portion 2a after being removed, and the front tonneau cover 20 and the rear tonneau cover 30 do not get in the way.

In this embodiment, the slide mechanism 40 is configured to move up and down in conjunction with the opening and closing operation of the back door 4.
Thereby, when the back door 4 is opened and closed, the rear end of the front tonneau cover 20 and the front end of the rear tonneau cover 30 always move up and down.
For this reason, the opening part TO at the rear of the tonneau cover device 10 can be enlarged simply by opening and closing the back door 4, and the loading and unloading of the luggage into the luggage compartment T can be performed easily.
Therefore, the operator can easily put in and out the luggage into the luggage compartment T without separately opening and closing the tonneau cover device 10 alone.
In this embodiment, the slide mechanism 40 includes a wire member 42 in which the upper end portion 42b is fixed to the back door 4 and the intermediate portion 42a is fixed to the slider member 41 (see FIG. 5). .
Thereby, the opening / closing operation | movement of the tonneau cover apparatus 10 can be produced using the opening / closing operation | movement of backdoor 4 itself.
Therefore, the opening / closing operation of the back door 4 and the opening / closing operation of the tonneau cover device 10 can be mechanically linked with a simple structure such as the wire member 42, and the production cost can be reduced.

Next, a second embodiment will be described with reference to FIGS.
FIG. 17 is a side view of a cargo compartment equipped with the tonneau cover device of the second embodiment, and FIG. 18 is a schematic diagram of the opening / closing operation of the tonneau cover device, where (a) is in a closed state and (b) is in the middle of opening. The state, (c) is a schematic diagram showing an open state. In addition, about the component same as the above-mentioned embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  As shown in FIG. 17, the tonneau cover device 110 of this embodiment has a board member (124) on the rear side of the front tonneau cover 120 and a board member (121, 122, 121) on the front side, as opposed to the first embodiment. 123) and is set so as to cause valley deformation between the third board 123 and the fourth board 124.

  That is, as shown in FIG. 18A, the shelf 106 that supports the front tonneau cover 120 has an upper stage 161 as its front side, a lower stage 162 as its rear side, and an inclined part 163 that is rearwardly lowered at its middle position. Thus, when the front tonneau cover 120 is displaced upward, it is set so that valley deformation occurs between the third board 123 and the fourth board 124.

The opening / closing operation of the tonneau cover device 110 will be described with reference to FIG.
In the closed state of (a), since the slider member 41 is positioned at the lower end of the slide rail 8, the front tonneau cover 120 is also the rear tonneau cover 130 is also deployed in the luggage compartment T upwardly in a substantially horizontal state.

However, as shown in an open state midway of (b), when the slider member 41 is moved in the slide rail 8 intermediate position, the fourth board 124 from the rear by pressing forward, the front end 124a of the fourth board 124 Thus, a movement that causes the user to sink under the third board 123 is generated. As a result, a valley break occurs between the third board 123 and the fourth board 124.

  That is, as shown in (a), since the bending angle γ formed between the third board 123 and the fourth board 124 is formed upward, this bending portion R becomes a “trigger” and valley folding deformation occurs. It happens.

  Furthermore, in this embodiment, since the position of the engaging boss portion 36 of the winding unit 31 is also set above the plane extension line S of the third board 123, the valley fold deformation is further promoted. .

  And in the open state of (c), the 2nd board 122 is also pressed from back, the rear end 122a is displaced so that it may move upwards, and it is displaced upwards together with the 3rd board 123 and the 4th board 124. . In this way, the opening TO at the rear of the luggage compartment is enlarged, and it becomes easy to take in and out the luggage from the rear of the vehicle body.

With this configuration, even in this embodiment, the third board 123 and the fourth board 124 of the front tonneau cover 120 can be bent by valley folding to enlarge the opening TO at the rear of the cargo compartment T. it can.
In particular, since the folded intermediate board members (the second board 122 and the third board 123) are not exposed to the lower side in the open state by being bent by the valley deformation, the board members 122 and 123 are There is no interference with the package when loading and unloading. Therefore, the loading / unloading of the luggage can be performed more smoothly, and the usability of the tonneau cover device 110 can be improved.
Other functions and effects are the same as those in the first embodiment.

Next, a reference example will be described with reference to FIGS. 19, 20, and 21.

FIG. 19 is a side view of a luggage compartment equipped with the tonneau cover device of a reference example , FIG. 20 is a side view of the cargo compartment when the tonneau cover device is moved upward with the back door closed, and FIG. It is a system block diagram which controls a tonneau cover apparatus. In addition, about the component same as the above-mentioned embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

The tonneau cover device 210 of this reference example is configured to slide the slider member 41 using the electric actuator 200 without using the opening / closing operation of the back door 4.

  Specifically, as shown in FIG. 19, an upper pulley 201 and a lower pulley 202 are installed above and below the slide rail 8, and a belt member 203 is wound between the upper pulley 201 and the lower pulley 202. The slider member 41 is fixed to the belt member 203, and the belt member 203 is configured to be driven by an electric actuator 200 such as a stepping motor.

  The electric actuator 200 is controlled by the system block shown in FIG. The CPU 204 that controls the electric actuator 200 is connected with a vehicle speed sensor 205, a back door sensor 206, and a manual button 207 as input means. The vehicle speed sensor 205 is used to stop the vehicle, and the back door sensor 206 is used to open and close the back door 4. The state / manual button 207 is configured to capture an operator's opening / closing operation request.

  The CPU 204 performs arithmetic control based on the information thus acquired, and outputs an open / close signal or the like to the electric actuator 200 that is an output means.

Therefore, for example, as shown in FIG. 20, it is possible to obtain a state in which the tonneau cover device 210 is opened although the back door 4 is closed regardless of the opening / closing operation of the back door 4.
By obtaining such a state, it is possible to obtain an advantage that the luggage can be accommodated even when the luggage in the luggage compartment T cannot be accommodated in the luggage compartment T when the tonneau cover device is deployed. .

  Although not shown, since the opening / closing speed of the tonneau cover device 210 can be set independently of the opening / closing speed of the back door 4, the opening / closing operation of the tonneau cover apparatus 210 can always be the same speed.

As described above, in the reference example , the slide mechanism 40 includes the electric actuator 200.
Accordingly, the tonneau cover device 210 can be freely opened and closed regardless of the opening and closing operation of the back door 4 itself. Further, since the opening / closing speed of the tonneau cover device 210 is not restricted by the opening / closing speed of the back door 4, the tonneau cover apparatus 210 can be freely opened and closed.
Therefore, the degree of freedom of the opening / closing operation of the tonneau cover device 210 can be increased, and the functionality of the tonneau cover device 210 can be further enhanced.
Other functions and effects are the same as those in the first embodiment.

Next, another reference example will be described with reference to FIGS.

FIG. 22 is a side view of a luggage compartment equipped with a tonneau cover device of another reference example , and FIG. 23 is a side view showing a storage state of a front tonneau cover and a rear tonneau cover. In addition, about the component same as the above-mentioned embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

In the tonneau cover device 310 of this reference example , the front tonneau cover 320 is also constituted by a winding type tonneau cover. In other words, not only the rear tonneau cover 30 but also the front tonneau cover 320 is constituted by a winding type tonneau cover so that the entire cargo compartment T is covered by the sheet members 321 and 32.

  As shown in FIG. 22, the front tonneau cover 320 includes a winding unit 332 installed so as to extend in the vehicle width direction behind the seat back 1 </ b> A of the rear seat, and a seat member 321 pulled out to the vehicle body rear side. The take-up unit 332 is provided with a take-up roller 333 biased in the take-up direction. Among these, the front-end | tip part 321a of the sheet | seat member 321 is being fixed with the fixing pin 334 (refer FIG. 23) with respect to the latching piece part 35 of the winding unit 31 by the side of the rear tonneau cover 30. FIG.

With this configuration, when the slider member 41 of the slide mechanism 40 moves up and down, not only the sheet member 32 of the rear tonneau cover 30, so that the sheet member 321 of the front tonneau cover 320 is also moved up and down.

In particular, as shown in this reference example , the front tonneau cover 320 is constituted by a winding type tonneau cover, so that it is not necessary to consider the bending direction or the like as with a board member, so that components such as shelves are unnecessary. It becomes.

  When the tonneau cover device 310 is removed and stored in the sub-trunk portion 2a, the sheet members 32 and 321 are wound into the winding units 31 and 332 as shown in FIG. Since only two engagement handle portions 33 are provided, the board member can be accommodated in the sub-trunk portion 2a more compactly than in the first embodiment in which the board member is folded.

Thus, in this reference example , the front tonneau cover 320 is formed of a winding type tonneau cover.
Thereby, since the front tonneau cover 320 and the rear tonneau cover 30 can be configured without using a board member, the large tonneau cover device can be made more compact in a state where it is removed from the vehicle body in the unfolded state.
Therefore, the front tonneau cover 320 and the rear tonneau cover 30 can be more compactly accommodated in the sub trunk portion 2a after being removed, and the front tonneau cover 320 and the rear tonneau cover 30 do not get in the way.
